With a profesional scotopic/photopic light meter. These cost $ 2,200.
Scotopic lumens are a unit of measurement for the total amount of light emitted by a light source that is visible to humans in low light conditions. It quantifies the light output of a source under conditions where only the rod cells in the human eye are active, typically in low light or night-time situations.
This website should clear up any questions you have about the disorder: http://www.readingandwriting.ab.ca/judypool/irlen.htm If not, you can just google scotopic sensitivity disorder, and you should find thousands of sites describing it. Hopefully this helps, if it doesn't, then I'll be happy to answer any other questions you may have.
Scotopic vision occurs in low-light conditions and is mediated by the rods in the retina. It provides black-and-white vision with low visual acuity. Photopic vision occurs in bright light and is mediated by the cones in the retina. It provides color vision and high visual acuity.
Rods are the photoreceptors that are not used in color vision. Rods are much more plentiful than the cones, and much more sensitive, they are responsible for scotopic vision.
For maximum utilization of scotopic vision( a vision of eye in low light), 20 to 30 minutes in total darkness are required to attain satisfactory retinal dark adaptation. An alternative is to have the aircrew member wear red goggles for 20 to 30 minutes before flying. When worn in normal illumination, red goggles will not interfere significantly with the ability to read most maps, charts, manuals, etc., as long as the printing is not in red ink. Red goggles block all light except red, which enhances rod dark adaptation because red light does not stimulate the scotopic system.

night blindness is particularly caused by deficiency of vitamin A (retinol)Our eyes contain 2 photosensitive cellsrods-for scotopic vision i.e., for night vision contain pigment rodopsincones-for photopic vision i.e, to see colours in presence of light contain pigment ionopsinrodopsin pigment contain retinal, an aldehyde of retinol(vitamin A)Therefore deficiency of vitamin A effects scotopic vision and is known as night blindness

The rods in the retina are responsible for night vision. They are sensitive to low light levels and help us see in the dark. Rods are located around the periphery of the retina and are most active in dim light conditions.
